CULTIVATOR FOR LISTED CORN.

SPECIFICATION forming part. of Letters Patent No. 396,805, dated January 29, i889.

Application filed May 25, 1888. Serial No. 275,103. (No model.)

To a'ZZ 2072/0721 2 may concern:

Be it known that I, JosEPH 'W'. Brown, a citizen of the United States, residing at Miltonvale, in the county of Cloud and State of Kansas, have invented certain new and useful Improvements in Cultivators for Listed-Corn; and I do hereby declare the following to be a full, clear, and exact description of the inention, such as will enable others skilled in the art to which it appertains to make and use the same.

This lllVOl'llllUll relates to cultivalors for listed corn of the class shown in the patent issued to me on April 3, 1888, No. 38.05%); and it consists in the novel improvements in the construction of the cultivator, and in the combination of the parts, ashereiuaft er fully described and claimed.

In the drawings, Figure 1 is 'a side view of the cultivator, and Fig. 2 is a plan view of the same.

A is the main frame, and B is a roller formed in four sections and journaled upon the shaft 1%, which is secured in the frame A. The outer sections, 5, of the roller are cylindrical and roll the side ridges. The inner sections, 1), are double cones, and they roll the central ridge for the seed-corn, the waterchannels being formed by the angular portions 0. Vashers c are interposed between the sections of the roller to reduce the friction and allow them to turn freely when the cultivator is turned around at the end of a row.

O is the seat for the driver.

I) is a triangular frame secured in front of the main frame by the clamps d.

D are handles secured to the triangular frame, and d are braces for supporting them.

E are the small plows for throwing up the ridge of soft earth. in the middle of the trench, and F are the blades behind them.

G is a spacing-wheel for the seed-corn, pivoted on the pin g at the end of lever G. The seed-dropping mechanism is not shown, as it may be constructed in various approved ways. The lever G is pivoted to the top of the uprights H at the front of the triangular frame, and h are braces for supporting the said uprights.

H is a clevis for drawing the machine alon I is a tongue pivotedon the pin 1', which passes through the rqn'ights ll, and t is a neck-yoke at the front end of the tongue.

J is a sleeve which is journaled upon the spindle j, extending between. the handles D, and His an arm secured to the said sleeve and connected to the tongue by the chain 7r. A second chain, Z, also connects the said arm with the lever G.

M is a hand-lever secured on the roller J, and provided with a spring-catch, m, which looks into the notches of the quadrant N and secures the tongue and seed-wheel lever at any desired elevation. When the machine requires to be turned around at the end of a trench, the tongue and seed-wheel lever are moved to the positions indicated by the dotted lines in Fig. l by means of the hand-lever M. This causes the cultivator-blades to be raised clear of the ground, and, the roller be ing formed in separate sections, the machine can be turned in either direction with great facility.

N is a scraper provided with supportingarms n, which are pivoted to the rear of the main frame. The scraper is adapted to bear upon the roller, and is provided. with the handle 0, also pivoted to the frame.

P is a spring which is attached to the said handle and to the under side of the seat, and which holds the scraper clear of the roller while the cultivator is at work in the trench. 'When too much dirt adheres to the surface of the roller and prevents it from working properly, the driver can clean it off by merely depressing the handle which projects from under his seat. 'When the handle is let go, the spring raises the scraper clear of the roller.

\Vhat I claim is r 1. In a cultivator for listed corn, the combination, with afran1e,of a tongue pivoted to the front end of the frame, a hand-lever connected to the rear end of said tongue for raising the front end of the frame, a sectional listertrench-rollerjournaled at the rear of the frame, and the blades secured to the frame in termediatebetween the said tongue and roller, substantially as and for the purpose set forth.

2. In a cultivator for listed corn, the combination, with the frame, of the uprights secured to the front end of the frame, the tongue pivoted to said uprights, an arm and a hand lever pivoted to the frame, and a chain connecting the free end of the arm with the rear end of the tongue, substantially as and for the purpose set forth.

3. In a cultivator for listed corn, the combination, With the frame, of the uprights secured to the front end of the frame, the tongue and the spacing-Wheel lever pivoted to said uprights, an arm and a hand-lever pivoted to the frame, and separate chains con neetin g the said arm with the rear end of the tongue and with the said lever, respectively, substantially as and for the purpose set forth.

4. In a cultivator for listed corn, the combination, with the listing trench-roller, of the scraper bearing against the surface of the roller and provided with a proj eeting handle, the arms projecting rearwardly at right angles to the scraper and pivoted to the frame, and the spiral spring secured to the seat and holding the said scraper clear of the roller, substantially as and for the purpose set forth.
